Nice place, very clean and well furnished, located on Soi Sukhumvit 22. Through the parking of the Mariott's hotel you can walk to the Benchasiri's park and to the BTS Phrom Pong. My host bought a clothes rack, a laundry basket and a bathroom shelf as I was there. She wants to do it's best for the gests.
She is really nice and very helpfull. She answered very quickly to all my requests. You have a washing machine and a dryer in the common area for a few THB.
I enjoyed a lot staying there.
